This map is the crime rate per capita in each New York Police Department (NYPD) precincts in 2018. Be wary: the data was described as only "valid" complaints but does not explain what "valid" means. One's judgement of the map may be biased because of conclusions we make about certain pieces of data. For example, crime rate per capita does not necessarily mean that one area is more "dangerous" than another; it may simply mean that an area has a smaller population and therefore a smaller denominator when computing the per capita rate.
This map shows the poverty rate per capita in each New York City neighborhood in 2018. There is a clear visual correlation between poverty rate and crime rate, which may help users make conclusions about actions they can take to reduce crime in cities like New York. This does not imply a causation, but problems of poverty and crime in specific areas must be addressed by activists, leaders, and legislators.
This map shows the violent crime rate per capita in each New York City precinct in 2018. The National Institue of Justice describes the following crimes to be considered violent: rape and sexual assault, robbery, assault, and murder. The crime rates of some of these major felonies have gradually changed over time. Note that the y axis is on a logarithmic scale so that trends of low-frequency crimes are visible.
